Outbuildings in Chelmsford
Quality Outbuildings in Chelmsford
An outbuilding is a great way to add space to your property without extending the house itself. It gives you somewhere to work, exercise, entertain or store the things you love. With Chelmsford’s wide variety of homes, many Chelmsford properties have room for a well-built garden building.
We handle the whole project: groundworks and foundations, drainage and services, the brick, block or timber-framed structure, roofing and finishing.

Outbuildings in Chelmsford: Local Knowledge
Chelmsford is the county town of Essex and was granted city status in 2012. It’s also known as the birthplace of radio, thanks to Marconi’s pioneering factory. The city and its surrounding suburbs contain every type of home, from Victorian terraces near the centre to post-war estates and new developments on the outskirts. Planning and building control are handled by Chelmsford City Council, and Essex Highways manages the roads and footways.
Our office in Hutton is around 9 miles from Chelmsford as the crow flies, so we are close at hand for site visits and while your project is on site. We also work regularly in nearby Writtle, Margaretting and Highwood.
Planning & approvals in Chelmsford
Chelmsford is in the CM1 and CM2 postcode area, and planning applications and building control for projects here are handled by Chelmsford City Council. We work alongside you, your architect and the council from the start, so the right approvals are in place before work begins. Essex Highways looks after the roads and footways, which matters for anything that affects the public highway, such as skips, deliveries, drainage connections or a dropped kerb.
Why use a local builder?
Being based in Hutton means we know the ground conditions, councils and suppliers around Chelmsford. You deal directly with Mark or Tom Boswell, who can visit your property, talk through your plans and give you an honest quotation.
Planning
Do I Need Planning Permission for an Outbuilding in Chelmsford?
Many outbuildings can be built under permitted development rights, without a full planning application, as long as they meet limits on size, height and position in your garden. Listed buildings, properties in conservation areas and outbuildings used as separate living accommodation may need planning permission.
We’ll give you straightforward advice at the site visit and, where planning or building regulations approval is needed, work with your architect and the council to get it in place.
Permitted development
Many garden rooms, home offices and garages fall within permitted development limits. We’ll help you check before work starts.
Annexes & living space
Outbuildings used for sleeping or as separate accommodation usually need planning permission and building regulations approval.
